At present, in the connection between the existing civil tap water pipe fittings, threads are required to be processed before the end parts of the water pipes are connected, and the connection and installation are very inconvenient. The sealing means of the joint is generally flexible plastic wrapped around the end of the connecting tube or a rubber-based sealing gasket is used. When the screw thread is screwed, the sealing material between the pipe fittings is also twisted while being pressed because the two connecting piece parts rotate in opposite directions, and liquid leakage is easy to generate.
On the other hand, the pipe joint for the oil and water pipelines at present consists of a joint, a pipe nut, a clamping sleeve and a connecting pipe, the service life is long, and leakage often occurs at the matching position of the clamping sleeve and the connecting pipe. When the pipe nut is used for tightening the clamping sleeve to prevent leakage and not work, the following two modes are adopted to solve the problem of leakage of the joint: the universal pipe joint has the defects that the pipe network is easy to leak due to weak locking force; although the copper hoop pipe joint has strong locking force, the cost for locking the two ends is high.
To this end, we propose a flanged copper ferrule tube fitting.
